All Relics Captured Message

[brian]

Future perfect tense implies that victory will occur by the time the timer finishes.

Future tense implies that victory will occur when the timer finishes.

I would change the message when all relics are captured from the future perfect tense "will have won" to just future tense "will win".

My teachers already told me to not mix future and past tense in the same sentence for no reason, well.

While at it, adding a period. (Reason: All messages in the middle of the screen end with an exclamation mark except the ones here and the Wonder victory ones. If the english or translated strings ever use 2 sentences, it would be obvious that sentences must end with a period. This is also the reason why many tooltips in ​Phab:D594 now need a period.)

Not sure about those capitalisation changes. English have some rules about those when it comes to titles.

In 20000:

Fix some string issues and reveal the name of the next release (Ken Wood).

Change the tense of the Capture The Relic message, as proposed by brian (WhiteTreePaladin).
Consistently use title case for buttons.
Use more descriptive and concise option titles.
Remove two unused strings.
